Formatting microSD

Hello, I'm having difficulty formatting a 2gb Sandisk micro SD card.
I originally had autonooter 2.0 burned onto it and i remember i used it for other disk images when i first rooted my nook color.
Now i'm trying to help a buddy of mine and trying to burn a 2gb image of CM7 onto it.
I erased everything on the card and tried to format it on my PC and it showed only a few MBs of memory... i knew it was something i wasnt doing correctly but i decided to try formatting it from my phone which sort of worked
It freed up 1.84 gb, and left some random files from the phone.
I searched around and figure it has to do with the card being partitioned and such, but i dont really know what i'm supposed to do about it.
The disk image im trying to burn is 1.86 gb, so i know that there's something on the card i didnt wipe properly.
Thanks in advance for any input.

You formatted, which got rid of the low capacity from the image. Now you just need to delete the files and directories that the phone dropped onto it; you can do that from windows explorer or whatever.
Iirc, a 2gb card actually is 1.86gb, so you won't get more than that. And that's probably why the image you want to use is exactly 1.86gb.

If you have a windows pc, you can try the utility SDFormatter to format you microSD.
Good luck.

[Q] Upgrading from 4gb sd to 8th sd?

So all i want to do is take everything off my 4gb sd card and use an 8gb sd card so that I have more storage space. Everything works great as is, and I wanted to keep everything as is. Just need more storage space. I've looked through the forums and haven't found anything that addresses this process. I am running CyanogenMod 7.0.3 w/a 4gb sandisk micro sd card. How do I copy so that it boots just like my 4gb card???? Thanks ahead of time for any help.

I recommend just writing an image file with winimage. Then writing it to a 8gb card, then using Easeus Partition manager to expand the last partition to full 8 gb.'

Do you boot from the SD card or eMMC?
If it's the latter, just copy the contents of the old card to the new one.
If it's the former, I recommend a fresh install; use a backup program (MyBackup, Titanium Backup) to back up your Apps and Data and then restore when you're done with the fresh install.

I'd like to do this as well.. in response to previous reply.. there are 4 partitions (boot, 2 other and last one with your data) do I have to create 4 different images with winimage or just for the first boot partition or does the winimage creates the image of the whole msd card?

The winimage will create a 4 gb image of your card on the 8 gb cards including existing partitions. What you'll need to do is get the largest partition to expand to the whole card. Assuming that the 4gb install on SD is the same as an 8 gb install if you did it fresh.
If the partitions are set different for 8 gb on a fresh install, you're better off just doing a fresh install and use titanium backup as the other guy said.

That's a good point, the Size-agnostic SD installer uses different partition sizes for everything except the boot partition depending on the size of the card.

I tried winimage first to see if it even worked. Which it didn't. I didn't try to expand the existing partition. It just booted as a normal nook. You would think this would be a easy process but.... Lol, always new challenges. Guess that's why I enjoy doing this.

Well I tried yet again w image, expanded the partition. Still. Didn't work. I must be missing something. How hard can it be to make a copy of a bootable card? Must b brain dead today! Any other thoughts? Thanks!

I have done this several times, and I recommend downloading easus todo backup free. Then place both sdcards in a card reader, run todo backup and just copy the 4g to the 8g and expand the fourth partition right there in todo.
This applies especially if you want to copy to same size sd's, as you will not run into the usual image sizing issues.
Hope this helps

I don't know what you're doing wrong. before expanding the partition, make sure the sd boots, if it doesn't, then there's a problem with image being read or written as opposed to the partition.

I also had a problem with a new SD card not booting that I fixed by using the nook (that is the core nook OS) to reformat the card, then put the image onto the SDcard (shouldn't have changed anything as far as I know, but it did anyway).

Ok I tried this and it worked flawlessly. Used win32diskimager to "read" my 4gb sd with cm7 image. and then used "write" to 8gb sd card. It cloned 4 gb original image with 4 partitions and one unused partition of 4 gb. After that used easeus partition manager(latest version) to format unused pattition to fat32 and then merged with last partition of 2gb (move/resize) ..so now I have 6 gb of data partition which i can use to transfer files or move apps from nook's internal drive. The new 8gb card with cm7 image booted without any issues keeping my original settings of 4gb. One thing to mention that somehow it did not work on one pc with windows xp (kept getting write error on win32diskimager program)but worked on my laptop with windows 7.

That is exactly how I have done it in the past as I described in my first post. I don't know why a person would have trouble with it unless there was a format issue (i.e. ntsf, etc).

[Q] SD card partition problem

So I am running CM7 off of an sd card in my nook color.(Using http://forum.xda-developers.com/showthread.php?t=1904129 and I highly recommend). Win32discimager for some reason created a small partition just larger than the installer which remains on the card. I also have the android OS on the card that is taking up 1 gb partition. The rest of my 16gb micro sd card is labeled as the emmc for the tablet which is not what i intended. Now I cant load it up with my movies and videos like I had hoped.
Does anyone know:
Is there any way I can change these partitions on my card? (I have already tried EasuUS partition manager)
Where did the 1gb partition that android is on come from and why did the emmc get so large?
Is there any way to take the android image currently on my sd card and just putting onto the nook after I have already had it run from the sd card and then just formatting my sd card for storage?
There are probably newbie questions but I have tried to do my own research and havent found any certainties. Any help would be really appreciated.

Ok, first you need to go to my tips thread linked in my signature and read in section B how the verygreen SD works. You will understand the partition structure a little better.
Now for your sdcard/emmc media storage problem, you have a setting wrong in CM7. Go to settings, CyanogenMod settings, Application and uncheck "Use internal storage". What that setting does is swap emmc and sdcard so that your real sdcard is called emmc and internal media storage is called sdcard. It is not default that way. Somehow it got checked.

[Q] Best way to get SD card back after ManualNooter/flashing CM7?

I used Manualnooter to root my NC and am running CM7 now. The device was only recognizing the SD card as being 1GB, even though it's 8GB. I went into the Settings and formatted the SD card just like it suggests in the instructions here. However, it's just showing 1GB wih 875MB avail under "SD Card" within Storage Settings. When I hook it up to my PC, it connects as 2 drives. One is titled BOOT and one is just a Removable Disk which appears to be the active storage since it has some recent downloads and the BOOT doesn't. Both show 1GB capacity.
I want to get TWRP working but more importantly I want a functioning 8 GB card. I didn't post this in the MN app thread because I don't know for sure if that's what caused the problem or not. Please halp?

Used the Mini-Tool here to expand the partition: http://forum.xda-developers.com/showthread.php?t=2062357. I now have ~7GB free in \mnt\emmc and I guess that should do.
Let me know if there is a smarter way to go about doing this.

Don't know if TWRP has a 'partition SD card' option, but CWM recovery does and that is what I used to reclaim the extra space on my 16 GB SD card when cm10 was installed.

[Q] Max SD supported by recovery?

Hi,
I've noticed that my 64GB Class 10 Micro-SD is not mountable in recovery but have validated that a 8GB Micro-SD is mountable.
Is there a way to mount a 64GB in recovery? What is the max supported size in recovery?
Thanks!

Recovery does not care what size your sd card is. It does care how it is formatted.

Thanks for the response.
I let my S4 format the card. Is there a better way or so you know which format would be best.

The 64GB card comes exFAT formatted which is likely not supported yet by the recovery you are using.
If you can mount the sd card in a Windows PC you should be able to format it to FAT32 using the Windows disk management utility.
The downside to FAT32 is the 4GB file size limit.

Get EasyUS Partition Masters (GREAT PROGRAM and EASY to use) it can format your 64gb to FAT32. I did that with mine and it runs great in recovery. I had to do this on the SIII because i had like 5 roms i jumped from and these roms are not tiny.

Your welcome

So is FAT32 the ideal format (sans file size limits)? I just bought a Sandisk 64GB SDXC last night & it was immediately not recognizable by the phone when installed. I formatted it to FAT32 & phone still doesn't recognize it. Looking for feedback ASAP!

I actually ended up using my Mac to format as FAT and that did the trick.
Been a fully usable and recognized by the phone amount now.
Also fully recognized in recovery mode, which was important to me.

Ok, well, I just let the phone format the card, it formatted it as FAT32. I'm backing all the stuff off my 32gb card from my laptop back onto the card . . . then my music . . . after I verify it'll read the contents.

I actually did the same exact thing initially.
I put my 64GB micro-sd in, let the phone format it, loaded it up but then started to get errors reading the card and corruption warnings.
I couldn't see it or mount it when in recovery.
Android could still use it though.
If it took it out and connected it to a Mac or PC it'd not see it as a valid readable drive and would say it needed to be initialized.
It must be something about the way allowing the phone to format it but after formatting from my Mac it's been solid. No issues.

Well, phone formats it as FAT32. I stuck it back in my laptop, it was working. I copied a bunch of files to it, put it back in the phone, it was working, now back in the laptop copying my 30gb of music over. It seems to be working fine in the laptop. I hate messing with formatting/copying as it is just time consuming. I remember I thought I'd be sneaky & format some discs for a Synology NAS & copy the files over via SATA. That went over like a turd in a punchbowl because as soon as I plugged that formatted/loaded drive into the NAS, it didn't recognize it . . . and I had to do it all over again!

Ok, all 30GB copied music successfully & the apps see it no problem. I hope I don't have these problems others have had with these cards.
Thanks!
